Abstract: In one embodiment, an exploratory linktrace is initiated from an initiating network device with an exploratory linktrace message (ELM) having a target address. Each network device receiving the ELM may then propagate the ELM on a plurality of its ports to a plurality of downstream network devices based on the target address. In addition, each receiving network device returns an exploratory linktrace reply (ELR) for each of the plurality of ports, where each ELR is returned according to one or more mechanisms to mitigate stormed replies to the initiating network device.

Abstract: A method for communication includes associating respective feature chains with a plurality of interfaces of a data switch. The feature chains include service features. A respective failure policy is defined for each of one or more of the service features in each of the feature chains. Upon detecting a failure in a service feature in a feature chain associated with one of the interfaces, data packets are routed through the data switch while applying, responsively to the failure, the respective failure policy to the one of the interfaces.
